Title: A computer system and method for measuring an analyte concentration with an affinity assay
Inventor: BROWN EMERY N
IPC: G01N33/487
Filed: 1994-02-23
Abstract: A method for improved measurement of a concentration of an analyte in a sample having an unknown concentration of the analyte includes using an affinity assay having an experimental indicator. Standard and control samples, each having a known concentration of the analyte, are assayed and a response, an amount of experimental indicator emitted for each sample, is detected. The unknown sample is also assayed and its response is detected. A prior probability density is supplied for the unknown concentration, along with a model for a standard curve relating an expected response to a concentration of the analyte. A posterior density, having a median, for the unknown concentration is generated based on the supplied prior density, the supplied model, and the responses for the standard samples, the control samples and the unknown samples, by applying Bayes' rule. The median of the posterior density may be provided as the measure of concentration of analyte in the unknown sample, with an accuracy defined by the standard deviation of the posterior density. The standard curve preferably accounts for relative error due to experimental variation by using a random variable to represent variations on the analyte concentration scale due to variability in the preparation of samples in the laboratory. The minimal detectable dose for a single assay run may also be determined.

Abstract: PCT No. PCT/FR94/00724 Sec. 371 Date Dec. 13, 1995 Sec. 102(e) Date Dec. 13, 1995 PCT Filed Jun. 16, 1994 PCT Pub. No. WO95/01034 PCT Pub. Date Jan. 5, 1995For demodulating a phase-modulated signal having 2M states of a carrier (M being an integer), the signal is converted into two baseband signals in quadrature. For that, they are multiplied by a signal delivered by a local oscillator at a transposed carrier frequency. Then the baseband signals are digitized by sampling at the clock frequency of the modulating signal. The clock of the signal is recovered by adjusting the phase of a local clock, stabilized at a bit frequency. For that, a minimum value of the intersymbol interference is searched. The signal clock is recovered before the carrier is recovered. Devices for implementing the method are also disclosed.
